KOMBINAT4 is Audio Damage's fourth-generation flagship distortion. Take any sound, split it into up to eight frequency bands, and assign one of 38 distortion engines to each band. Or flip to Serial mode and chain those eight engines end-to-end for stacked, cascading mayhem. THIRTY-EIGHT DISTORTION ENGINES The complete roster from Kombinat Tri returns: Fuzz, Saturate, Distort, Clip, Warp, Degrade, Ring Mod, X Noise, Octaver, Wavy, Rectify, Tube Clip, and the famously unhinged Nerd Rage. Joining them is the entire engine set from our Grind distortion: Tanh, Asym Tanh, Overdrive, Polynomial, Linear Distort, Sine Drive, Var Hard Clip, Gloubi Boulga, MXR, Soft Clip, and Cubic NLD. Plus thirteen brand-new algorithms built specifically for Kombinat4: Wavefold, Chebyshev, Bitwise, Slew Limit, Comparator, Diode Clip, Feedback FM, Fractal, Dropout, Shapeshift, Phase Distortion, Stutter, and Erosion. Every engine has up to three custom-labeled controls plus per-band gain and solo. Pick a different engine for each band and design distortion tones that simply weren't available before. EIGHT BANDS, TWO MODES In Multiband mode, the input is split by Linkwitz-Riley crossovers into up to eight parallel bands. Each band gets its own engine and gain stage, and everything recombines at the output. Drop to two bands for classic low/high splits, push to eight for full-spectrum surgical distortion design, and solo any band to dial it in cleanly. In Serial mode, those same eight slots become a chain — every engine processes the full-bandwidth signal in turn, for layered drive structures impossible to achieve with a single algorithm. OUTPUT SECTION A dedicated output filter with twelve types: 2-pole and 4-pole low-pass, high-pass, and band-pass shapes, a notch, three OTA-style filters, a 914-style ladder bandpass, our Filterpod, and bypass. Built-in Rough Rider compressor at the output with sidechain HPF and external sidechain input. Global feedback path with attack and decay envelope for self-oscillating screams and slow-blooming sustain. Optional AGC for level-matched A/B comparisons across heavy distortion settings. DC blocker. 2x and 4x oversampling for clean high-frequency content. PRESETS AND WORKFLOW Factory preset library covering subtle saturation, mix-bus enhancement, mid-range fattening, lead guitar tones, low-end mangling, full-on industrial destruction, and everything in between. Folder-based user preset browser with favorites and import/export of single presets or full folders as ZIP. XML preset compatibility with the desktop edition — your iOS presets work in your DAW and vice versa. AUv3 plugin for iOS hosts including GarageBand, Logic Pro for iPad, AUM, Cubasis, Loopy Pro, Audiobus, drambo, BeatMaker 3, and others. Standalone app included. Tooltips on every control. Animated band display with realtime spectrum overlay. No DRM, no account, no online activation.

Fields is a portable field recording app for capturing, organizing, and editing sounds in one place. Record sounds wherever you are, organize them with photos, notes, and locations, and edit your recordings directly in the app. Capture new material with the built in microphone or an external audio interface, import existing audio files, and keep everything organized in one place. Fields includes useful editing tools such as cut, copy, crop, reverse, fades, gain, normalize, filter, pitch, speed, trim silence, and noise reduction. A pre roll buffer helps you save sounds that happened just before you pressed Record, while automatic location tagging and the built in map make it easy to remember where each recording was captured. Your recordings belong to you. Fields requires no account, uses no tracking, and lets you choose between iCloud and Local Storage.

Verdict
The clearest difference is update cadence: Kombinat4 at every 3 days against Fields's every 6 weeks. Kombinat4 also leads on rating (5.0 vs 4.7) and iOS requirement (12.0 vs 15.0). On price, review sentiment, ratings volume and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Kombinat4 costs $7.99 and Fields $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Kombinat4 holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 10 and 13 respectively. Written reviews complicate that: 67% of Kombinat4's written reviews are positive against 73% of Fields's, so the app with the better star average is not the one people write more warmly about.
Kombinat4 ships an update every 3 days, Fields every 6 weeks. The most recent releases landed on October 22, 2026 and October 15, 2026 respectively.
